The gold-platinum premium dropped to below $150 an ounce,its lowest since early July, after hitting a record above $230just last week as grim economic prospects weighed on platinumwhile gold was supported by hopes for more monetary stimulusfrom central banks around the world.

As the gold-platinum spread has shrunk to a multi-week low,some investors may start to reverse their recent tradingstrategy of buying platinum and selling gold, he added.
